SPECIFICATION forming part of Letters Patent No. 618,824, dated February7, 1899.

Application iiled July 27, 1896. Renewed June 18, 1898. Serial No.683,869. (N0 mOClel-l To @ZZ whom t may concern:

Be it known that I, THOMAS E. BARR, a citizen of the United States,residing at the city of Kalamazoo, in the county of Kalamazoo' and Stateof Michigan, have invented a certain new and useful Roller Window-Screenfor Oar-Vindows, of which the following is a specification.

My invention relates to improvements in roller window-screens, and moreparticularly to improvements in roller window-screens for car-windows.

The objects of my in vention are, first, to provide a window-screenparticularly adapted for use in adouble glass car-window; second, toprovide a roller window-screen apparatus so constructed that it can beeasily removed for repair or opened for the purpose of cleaning; third,to provide a roller screen apparatus for a car-window which shall assistin the exclusion of water and dust from the car; fourth, to provide animproved means of detachably attaching the window-screen to the rail ofthe sash, and further objects appearing definitely in the detaileddescription. I accomplish these objects of my invention by the mechanismand means described in the following speciiication and illustrated inthe accompanying1 drawings, in which- Figure l is an interior view of acar-window with one of my improved window-screens in place. Fig. 2 is anenlarged detailsectional view on line 2 2 of Fig. l, looking in thedirection of the little arrows at the end of the section-lines. Fig. 3is a longitudinal section al view through the roller-casing, showing theroller complete inside, taken on line 3 3 of Fig. 4. Fig. 4: is anenlarged detail sectional view taken on line 4 4: of Fig. 3, looking inthe direction of the little arrows at the end of the section-line. Fig.is an enlarged detail elevation view of one of the clasping devices fortaking hold of the top of the window-screen. Fig. 6 is an enlargeddetail view of one of the loops 011 the upper edge of the,window-screen.

Similar letters of reference refer to similar parts throughout theseveral views.v

Referring to the lettered parts of the drawings, A represents the insidewindow-sash; A', the outside window-sash. Theroller J is supported in acasing between the bottom rails of the sash, the inner bottom rail beinghollowed out to receive the casing-wall B. The casing-wall B can be ofmetal covered with veneer to give it the appearance of they finish ofthe inside of the car, or it can be of any suitable material paintedv tosecure that effect.

On top of the window-sill D is placed a strip K, which'eXtendsunderneath the roller J On the outside of the roller the casing iscompleted by a fiat strip of wood or metal G, which is detachablysecured, preferably by wood-screws, to the bottom strip K and to thebrackets M M at each end. The roller is a spring-roller having a roundjournal in the bracket M at one end and a square shank to fit into thebracket at the other end. The socket in the bracket M' has an opening onone side, which permits of the easy removing of the roller.

The screen or wire net L is secured by one end to the roller andprojects out between the casing-wall B andG at the top. The upper end ofthe wire screen is secured by a metal binding H by seaming it into thesame. The binding extends outwardly and forms a cap which closes downover the upper edge of the strip G, forming a finished joint, which isvery smooth and practically closes the opening into the roller-casing.On this binding H, I place upwardly-extending loops I, by which meansthe screen is attached to the bottom rail of the outer sash A'. On theinside of the base-rail of the outer sash I secure an attaching devicefor securing the upper end of the screen through the bottom rail. Thereare a number of these attaching devices, varying according to the widthof the sash. For the ordinary car-window, as shown in the drawings, twowill be found to be sufficient. These fastening devices are clearlyillustrated in Figs. 2 and 5. A plate something like an escutcheon issecured to the sash-rail. Projecting out from this plate is a sash-plateE. In a suitable recess in the back of the plate is supported a leverhaving a downwardlyextending hook portion F and an outwardlyextendingbroadened portion F to serve as a thumb-piece for actuating the same.The point of the hook projects outwardly from the base-rail and is heldnormally in that position by the spring ct. A guiding-loop a is formedin the plate, into which the hook F extends, while it serves as a keeperfor the hook and a guide for the loop I, which is on the upper edge ofthe screen. The edge of the screen passes up in the slotted tube C oneach side when the screen is operated. From this description therelation and operation of the parts will be apparent. When thewindow-sash is lowered, the hooks F engage the loops I on the top of thescreen and when the window is raised carry the screen up to cover theopen space. When it is desired to open the window Without the screen,the operator presses his thumb on ends F F of the lever, and the hooksdisengage the loops, and the window is raised without the screen. Thescreen remains in the lower position Within its casing, where itpresents a very neat and finished appearance.

I desire to state that my improved car-window screen can be considerablyvaried in its details without departing from my invention.

' While the parts here shown coact together in a very satisfactorymanner and form a very desirable combination, the parts can beconsiderably varied. The casing for the roller at the bottom couldeasily be made entirely removable. The engaging hooks F on the sashcould also be modified, and while the formation of the binding into thecap for the upper edge of the outer roller-casing is very desirable onaccount of the strength and iinished appearance it gives to the Whole Iam aware that other constructions could be used instead and still make avery practicable car- Window screen. Other variations would no doubtsuggest themselves to those skilled in the art to which my inventionpertains.

I'Iaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a window-screen apparatus, the combination of the window-frame;the roller; a casing for the roller upon the window-sill the bottom railof the inner sash hollowed out to fit over the casing; the outersash-rail positioned to pass by the side of the casing; awindow-screening secured to the roller Within the casing projectingoutwardly and upwardly therefrom; a binding on the edge of the screenformed into a cap for the outer portion of the casing; loops I, on theupper edge of the binding; plates secured to the inside of the outersash-rail bearing suitable sashhold E; a lever with a hook portion F;extending down therefrom and an outwardlyprojecting flattened portion F,above the sashhold for actuating the saine, all coacting togethersubstantially as described for the purpose specified.

2. In a window-screen apparatus for double glass Windows the combinationof the roller J, supported on a suitable shaft; a casing-wall B, to theinside offthe roller and between the sashes of the Window; a removablecasing-Wall G, outside of the roller; a screen secured to said rollerprojecting outwardly between the two casings; a binding for the freeedge of the screen formed into a cap to shut down over the outer casingto protect the same and support the outer edge of the screen; andsuitable means of attaching the free edge of the screen to the rail ofthe outer sash, all coacting as described for the purpose specified.

3. In a window-screen apparatus, the combination of a suitable roller;screen attached to said roller; a binding on the free edge of saidscreen; loops on said binding; the sashrail; a plate on said sash-railbearing a sashhold; a lever with a hook portion pivoted to the saidplate having a flattened portion in the proximity to the sash-hold, allcoacting for the purpose specified.

4.. In a Window-screen apparatus, the combination of a suitable roller;screen attached to said roller; a binding on the free edge of saidscreen; loops on said binding; the sashrail; a plate on said sash-railbearing a sashhold; a lever with hook portion to engage said loops; akeeper and guide over said hook portion to guide the loops to place; allcoacting for the purpose specified.

5. In a roller window-screen apparatus the combination of a roller; acasing supported on the window for the roller with one side removable; ashaft to carry the roller; brackets within the casing containing openbearings to receive the shaft to permit the shaft and roller to beeasily removed without disturbing the remainder of the casing, asspecified.

In Witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
